A ranking order of ortho-lithiation directed by various functional groups in arenetricarbonylchromium complexes has been determined.This order differs from that found in the free arene series.Inductive effects were found to be the dominant factor for the determination of the site of lithiation.Fluorine was found the most powerful ortho direction of the groups studied.Additionally, fluorine was found to be a strong ortho director in the uncomplexed series under kinetic conditions.
